Specification of Letters Patent. Patented NOV, 3()9 19()9 Applicationaievaretuary 27, 1909. serial No. 480,474.

To all whom 'it may concern.'

Be it known that I, CHRISTOPHER C. SWAN- soN, citizen of the UnitedStates, residing at Laporte, in the county of Laporte and State ofIndiana, have invented certain new and useful Improvements in Wrenches,of

'which the following is a specication.

This invention relates to improvements in tools for removing nuts fromspindles and like devices and especially to a wrench which is adapted tobe used in connection with a nut and spindle which form the subjectmatter of a separate application for Letters Patent filed simultaneouslyherewith under Serial No. 480,475.

The particular object of this invention is to provide a form of wrenchwhich will not only release the nut from the spindle referred to butwill hold said nut embraced by the jaws `of the wrench until it isreturned to the spindle.

A further object of my invention is to provide a wrench which also maybe used on ordinary nuts within the capacity of the jaws of said wrench.

In the accompanying` drawing which forms a part of this application forLetters Patent, I have shown an improved form of my wrench inconjunction with the style of nut and spindle to which it is especiallyadapted in the following views:

Figure 1 is a sectional view taken through the end of a spindle and itsnut with my wrench applied to the latter; F ig.2 is a bottom plan viewof my improved wrench with a portion of the handle, and Fig. 3 is a topplan view of the wrench with a portion of the handle.

Referring to the details of the drawing 5 represents the end of aspindle which is longitudinally bored to receive a plug 6 which in turnis bored longitudinally to receive a bolt 7a on the outer end of whichis a rectangular head 7. An expansion coiled spring 8 is placed in thebore of the plug 6 and normally projects the bolt 7a to the eX- tentpermitted by a pin 4a which extends through the plug 6 and through aslot 4 in the bolt 7a. The outer face of the head 7 of this bolt isformed with a conical recess.v

12 represent the clamping jaws of the wrench which are cast integrallywith the handle 13 and with a central cylindrical boss 14, 14a. Theportion of the boss 14 projects between the jaws 12 while the portion ofthe boss 14a extends from the outer face or back of the wrench. Theseportions form a housing for a latch 15 the inner end of which isprovided with a head composed of a rectangular flange 16 and a conicalprojection 17 which is adapted to be seated when the wrench is appliedto the nut 9 in the conical recess in the outer face of the bolt 7Surrounding the latch l15 is a coiled spring 18 one end 19 of which issecured in a suitable opening in the boss 14 and the opposite end 20 isattached to a pin 21 in the boss 14a. This pin has a limited rotarymovement in a slot 22 which is cut in the boss 14a as shown in Fig. 3.The latch 15 is rovided with a thumb portion 23 by which it may beturned and also pushed inwardly against the tension of the spring 18.

In applying this wrench to the nut 9 the head of the latch is insertedthrough the opening 10 in the nut and the latch turned until the sidesof the ange 16 are out of registry with the walls of the opening 10. Thelatch is then pressed inwardly by the operator thus depressing the head7 of the bolt 7 a below the outer end of the spindle 5 and out ofengagement with the nut 9 so that by turning the wrench by its handle 13the nut may be unscrewed from the spindle 5. As the flange 16 willintersect the walls of the opening 10 it will be seen that the wrenchwill furnish a support for the nut 9 after the latter is unscrewed andthus be in position to return the nut to the spindle when the latter hasbeen oiled thus preventing the nut from becoming lost or coming incontact with the dirt and saving the lingers of the operator fromcontact with the grease and oil which usually attach to the ordinaryspindle nut.

It will be apparent that the form of iange 16 and opening 10 may varyfrom that shown in the accompanying drawing without departing from thespirit of this invention and that other modilications in detail may bemade without impairing the eciency of the device disclosed.

Having thus described my invention what I claim as new is 1.
